Default value is set when compiling the kernel. If it is set
to "Y", then there is no way of disabling the watchdog once
it has been started.
kdumptimeout Minimum timeout in seconds to apply upon receipt of an NMI
before calling panic. (-1) disables the watchdog. When value
is > 0, the timer is reprogrammed with the greater of
value or current timeout value.
NOTE: More information about watchdog drivers in general, including the ioctl
interface to /dev/watchdog can be found in
